In the description of the embodiments of the present application, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" herein is merely an associative relationship describing an associated obstacle, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more, and "at least one", "one or more" means one, two or more, unless otherwise specified.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

Wi-Fi (Wireless-Fidelity) refers to Wi-Fi operating in the 5GHz (5150 MHz-5825 MHz) radio frequency band and using the Institute of Electrical and Electronics Engineers (IEEE) standard. With the fact that 2.4G frequency bands used by Wi-Fi networks are more crowded and cannot meet development requirements, 5G frequency bands are opened in various countries successively, and compared with 2.4G Wi-Fi, 5G Wi-Fi has a higher wireless transmission speed. For example, the 2.4G channel and 5G channel information involved in different Wi-Fi standards specified by IEEE may be as shown in table 1:

TABLE 1

At present, most of 5G Wi-Fi channels belong to military and civil mixed use, the development condition is complex, for example, the open 5G Wi-Fi channels in different regions are different; 5G Wi-Fi channel regulations in different countries may also change over time; also, for example, channels in the 5G band are divided into indoor channels and outdoor channels, wherein some countries stipulate that indoor channels cannot be used by devices operating outdoors, and so on. Different regulations cause the availability of 5G Wi-Fi channels to be different at different times in different countries and under different scenarios.

When new and old equipment are cloned by changing the machine, if the data quantity needing to be backed up is large, the 5G frequency band is used for data transmission, and the data transmission efficiency is greatly improved. Considering that the 5G frequency band is complex to use, when data cloning is performed in the 5G frequency band, new and old devices need to negotiate to determine a consistent 5G channel for interaction. In a possible implementation manner, the new device and the old device may select a certain channel from an intersection of 5G channels supported by both the new device and the old device for interaction, so as to implement data cloning on a 5G frequency band. The process may be referred to in particular by the flow chart shown in fig. 1.

Illustratively, as shown in fig. 1, a schematic flow chart of data transmission between old and new devices is shown. The process comprises the following steps:

s101 (a), the new equipment inquires a supported 5G channel list;

s101 (b), the old equipment inquires a supported 5G channel list;

s102, the old equipment sends a 5G channel list supported by the old equipment to the new equipment;

s103, the new device compares whether the 5G channel lists respectively supported by the new device and the old device have intersection or not;

there are two cases of alignment in this step: case 1, the two channels have an intersection; in case 2, there is no intersection between the two channels. Wherein:

if the comparison result is case 1, step S104 is executed, that is, the new device and the old device perform data transmission on the 5G channel supported by both sides;

if the comparison result is case 2, step S105 is executed, that is, the new device and the old device perform data transmission on the 2.4G channel.

The data transmission process shown in fig. 1 can be implemented by an application (App) installed on the new device and the old device (e.g., a clone application), and the process needs to be implemented on the basis that the clone application can obtain a list (or set) of 5G channels supported by the old device. However, in practical applications, some systems do not provide a standard interface for a chip 5G channel, and at this time, if a clone application installed on an old device is a third-party App, the clone application cannot query a 5G channel list supported by the old device, and a comparison between a new device and the old device cannot confirm a 5G channel commonly supported by both devices.

In view of the above problems, an embodiment of the present application provides a data transmission method, where in a case where a 5G channel list supported by an old device cannot be obtained, a new device searches for a Wi-Fi connection request of an old device end on a 5G channel supported by the new device according to a preset rule, and when a Wi-Fi connection request sent by the old device is successfully searched on a certain channel, a Wi-Fi connection is established with an opposite end, so that a possibility that the new device and the old device perform clone data transmission on the 5G channel is improved, and user experience is improved.

Exemplarily, as shown in fig. 2, a schematic diagram of a system architecture to which a data transmission method provided in the embodiment of the present application is applicable is shown. The system architecture includes a first electronic device 100 and a second electronic device 200.

In some embodiments, the first electronic device 100 may be, for example, a receiving device for cloning data, and the first electronic device 100 may also be described as a receiving device or a receiving end below. For example, the first electronic device 100 may be installed with a clone application (e.g., a switch clone App), which may be used for interacting with a user, such as receiving a switch clone request input by the user, presenting the user with an old device type in which data to be transmitted is located, prompting the user for progress of data transmission, and so on. In this embodiment, the clone application may call a 5G channel list query interface of the first electronic device to query the 5G channels supported by the first electronic device 100. In addition, the first electronic device 100 may also have a bluetooth (bluetooth) communication capability, through which the first electronic device 100 may establish a bluetooth connection with the second electronic device 200; the first electronic device 100 supports Wi-Fi communication capabilities, which may include Wi-Fi communication capabilities over a 2.4G band, or Wi-Fi communication capabilities over a 5G band.

In some embodiments, the second electronic device 200 may be a sending device of clone data, and is used to send backup data to the first electronic device 100, and the second electronic device 200 may also be described as a sending device or a sending end below. For example, the second electronic device 200 may be installed with a clone application, which may be a third party application of the second electronic device 200 when the type of the second electronic device 200 is not the same as the type of the first electronic device 100. In this embodiment, the second electronic device 200 may not have a general interface for querying the 5G channel, that is, the clone application cannot actively query the 5G channel supported by the second electronic device 200. In addition, the second electronic device 200 may support a bluetooth communication capability, and may be capable of establishing a bluetooth connection with the first electronic device 100 through the bluetooth communication capability; the second electronic device may also support Wi-Fi communication capabilities, which may be Wi-Fi communication capabilities on a 2.4G frequency band or Wi-Fi communication capabilities on a 5G frequency band.

In some embodiments, the second electronic device 200 may be, for example, an old device used by the user in the past, and the first electronic device 100 may be, for example, a new device newly acquired by the user to replace the second electronic device 200. For example, the first electronic device 100 and the second electronic device 200 may be, for example, a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and other electronic devices, and the embodiment of the present application does not set any limit to a specific type of the first electronic device 100 and the second electronic device 200.

When a user needs to migrate data on old equipment to new equipment, the method for data transmission provided by the embodiment of the application can improve the possibility that the two parties transmit data on a 5G channel, thereby realizing the improvement of data transmission efficiency.

For example, as shown in fig. 5A to 5C, some Graphical User Interfaces (GUIs) that may be involved in the data transmission process provided in the embodiment of the present application are schematically illustrated. For convenience of understanding, the GUI shown in fig. 5A to 5C is used as an interface in the first electronic device 100, and the first electronic device 100 is a new mobile phone as an example for description.

In some embodiments, the new handset is installed with a change machine clone App, which may be a factory-owned application of the new handset (e.g., an application built into the handset manufacturer according to the android native scheme). After the user opens the switch machine cloning App on the main interface of the new mobile phone, as shown in fig. 5A, the new mobile phone may display the main interface after the switch machine cloning App is opened.

For example, a status bar may be displayed above the App host interface of the clone switch, and the status bar may include: one or more signal strength indicators for mobile communication signals (or cellular signals), one or more signal strength indicators for Wi-Fi signals, a battery level indicator for a handset, a time indicator, etc. Under the status bar, the switch machine cloning APP main interface may further include a relevant description of the switch machine cloning function, such as "migrating data of contacts, pictures, schedules, etc. to a new device at a fire speed" shown in fig. 5A; a device type selection area is also included below the functional description, in which the device types include a new device (this is a new device (reception data) "as shown in fig. 5A) and an old device (this is an old device (transmission data)" as shown in fig. 5A). In some embodiments, if the user currently operates the new mobile phone, the user may click and select an icon corresponding to "this is new equipment"; if the user currently operates the old mobile phone, the icon corresponding to the old equipment can be clicked and selected. For example, if the currently operated mobile phone is a new device, the user may input an operation 501 for an icon corresponding to "this is a new device", where the operation 501 may be, for example, a new device type selection operation such as clicking, long-pressing, and the like; when the new handset receives a new device selection operation 501 input by the user, an old device type selection page as shown in fig. 5B may be displayed in response to the operation 501.

For example, as shown in fig. 5B, the old device type selection interface may include a plurality of old device types for the user to select, such as the same old device type as the new handset (if the new handset is a glory handset, then one of the old device types displayed by the interface may also be glory), Android ^® Old device type (e.g. other Android than glory if old handset ^® The type can be corresponded to when using the mobile phone), iOS ^® Old device type (e.g. old handset using iOS if it is iPhone, iPad, etc ^® The devices of the system may correspond to the type).

In some embodiments, the old handset is assumed to be other Android of a different type than the new handset ^® The device, the user may input an operation 502 for an icon corresponding to another android device, where the operation 502 may be, for example, an old device type selection operation such as clicking, long pressing, and the like; when the new handset receives an old device type selection operation 502 input by the user, an old device selection interface as shown in fig. 5C may be displayed in response to the operation.

For example, as shown in fig. 5C, the old device selection interface may include a description for guiding the user to perform a connection operation on the old handset, such as "open a ' clone changed machine ' on the old device ', select ' this is the old device ', scan the two-dimensional code below to establish a connection"; the two-dimensional code required for establishing the connection between the new mobile phone and the old mobile phone can be displayed below the description content, wherein the two-dimensional code can be used for indicating a Service Set Identifier (SSID) and a password of a Wi-Fi hotspot of the new mobile phone, so that the new mobile phone and the old mobile phone can negotiate a Wi-Fi channel in the following process. According to the description information, the user can scan the two-dimensional code on the new mobile phone through the switch clone APP installed on the old mobile phone, wherein a schematic diagram of a two-dimensional code scanning interface of the old mobile phone can be as shown in fig. 6.

In response to the operation of scanning the two-dimensional code of the new mobile phone by the old mobile phone, the new mobile phone can establish a Bluetooth connection with the old mobile phone. Illustratively, the bluetooth connection establishment procedure may include: when the new mobile phone is not matched with the old mobile phone and the old mobile phone scans the two-dimensional code displayed by the new mobile phone, triggering the new mobile phone to open the Bluetooth function; then, the new mobile phone can send Bluetooth broadcast to the periphery; when the old mobile phone is in an inquiry Bluetooth scanning (inquiry scan) state, the old mobile phone can scan the Bluetooth broadcast sent by the new mobile phone; in response to the scanned Bluetooth broadcast, the old mobile phone can send a Bluetooth response to the new mobile phone, so that the new mobile phone acquires the old mobile phone as a pairable device option; the new handset may then send a page request to the old handset. The old mobile phone can monitor the paging request of the new mobile phone at a certain frequency modulation frequency within a fixed time window at fixed intervals, and after the paging request of the new mobile phone is monitored, the old mobile phone can send a slave paging response (slave page response) to the new mobile phone at the next time slot; after receiving the slave paging response of the old mobile phone, the new mobile phone can send a master paging response (master page response) to the old mobile phone in the next time slot; and then, completing pairing authentication of the old mobile phone and the new mobile phone, and establishing Bluetooth connection for data transmission.

It should be noted that, in the bluetooth connection process, the new mobile phone and the old mobile phone may establish the bluetooth connection in an implicit manner, that is, when the bluetooth connection is triggered to be established, the new mobile phone and the old mobile phone may not prompt the user to open information such as bluetooth, but may automatically start the bluetooth function, and complete the bluetooth connection establishment process without the user's perception.

In some embodiments, in order to avoid the problem that the bluetooth connection cannot be successfully established through the two-dimensional code, the old device selection interface may further include a prompt area for manually establishing the bluetooth connection between the new mobile phone and the old mobile phone. The prompt area may specifically include a description related to manual bluetooth connection establishment, such as "if scanning the two-dimensional code fails to connect, please click a manual connection below the scan interface of the old device, and connect to the WLAN below", and the local area network WLAN connection information and the password may be displayed below the description content. In addition, for the case where the old handset does not have the "clone-changed" application installed, the old device selection interface may also include an install link for the "clone-changed" application. For example, when the user inputs a selection operation for the "clone-changed" installation link (i.e., "please click here to install") in fig. 5C, the new handset may send installation information of the "clone-changed" application to the old handset through bluetooth communication, so that the old handset installs the "clone-changed" application based on the installation information.

It should be noted that the GUI schematic diagrams shown in fig. 5A to 5C are only examples, and in practical applications, the interface may further include other more icons or description information, which is not limited in this embodiment of the application.

For example, the first operation may include an operation of the user opening the receiving-end cloning application, an operation of selecting an old device type (which may correspond to operation 502 shown in fig. 5B), and the like. In response to the first operation, the first clone characteristic module generates a two-dimensional code, and sends the two-dimensional code to the first UX display module, where the two-dimensional code includes Wi-Fi connection information of the first electronic device, such as an SSID of a 5G Wi-Fi hotspot and corresponding password information.

For example, the second operation may be, for example, a start operation of a two-dimensional code scanning interface; in response to the second operation, the second clone characteristic module of the second electronic device may send two-dimensional code scanning interface start information to the second UX display module; in response to the two-dimension code scanning interface start information, the second UX display module may display a two-dimension code scanning interface (as shown in fig. 6), and scan the two-dimension code displayed by the first electronic device under the operation of the user, to obtain the two-dimension code data (that is, Wi-Fi connection information, such as SSID and password information of a Wi-Fi hotspot) of the first electronic device.

In some embodiments, the second UX display module of the second electronic device may send the obtained two-dimensional code data (i.e., Wi-Fi connection information, such as SSID and password information including a Wi-Fi hotspot) to the second clone feature module. After receiving the Wi-Fi connection information, the second clone characteristic module can send the Wi-Fi connection information to the second connection module, and instruct the second connection module to try to establish Wi-Fi connection based on SSID and password information of a Wi-Fi hotspot included in the Wi-Fi connection information; the second connection module may send the connection information to a second Wi-Fi module after receiving the Wi-Fi connection information, and instruct the second Wi-Fi module to attempt to connect to a Wi-Fi hotspot of the first electronic device.

The first Wi-Fi module stores 5G channel information supported by the first electronic equipment, and the second Wi-Fi module stores whether the second electronic equipment supports 5G capability, supported 5G channel information and the like. For example, the first channel negotiation module may perform a process of querying a self-supported 5G channel list, including: the first channel negotiation module sends first electronic equipment 5G channel query information to the first Wi-Fi module so as to query a 5G channel supported by the first electronic equipment; after receiving the 5G channel query information, the first Wi-Fi module may feed back a 5G channel list supported by the first electronic device to the first channel negotiation module, where the 5G channel list includes at least one 5G channel supported by the first electronic device.

The first channel negotiation module performing a process of querying a 5G channel list supported by the second electronic device may include: the first channel negotiation module sends 5G channel query information of the second electronic equipment to the first Bluetooth module; after receiving the 5G channel query information of the second electronic device, the first bluetooth module may send the 5G channel query information to the second bluetooth module via the bluetooth channel.

In some embodiments, on the second electronic device side, after receiving the 5G channel query information of the second electronic device, the second bluetooth module may send the 5G channel query information to the second channel negotiation module; thereafter, the second channel negotiation module may send the 5G channel query information to the second Wi-Fi module to query for the 5G channel supported by the second electronic device stored in the second Wi-Fi module. In a possible implementation manner, when the second Wi-Fi module does not have a general interface, the second Wi-Fi module cannot successfully acquire the 5G channel query information sent by the second channel negotiation module, and then does not perform 5G channel query, so that the second channel negotiation module cannot successfully acquire the 5G channel list fed back by the second Wi-Fi module. In this case, the second channel negotiation module may generate a 5G channel list, and the 5G channel list includes 5G channels that are empty.

In some embodiments, the second channel negotiation module may send a list of 5G channels supported by the second electronic device to the second bluetooth module; the second bluetooth module may transmit the 5G channel list to the first bluetooth module through a bluetooth channel. In some embodiments, on the first electronic device side, after receiving the list of 5G channels supported by the second electronic device, the first bluetooth module may send it to the first channel negotiation module. The first channel negotiation module may determine, according to the 5G channel list supported by the first electronic device and the received 5G channel list supported by the second electronic device, whether an intersection exists between the 5G channel sets supported by the two parties, that is, whether a jointly supported 5G channel exists between the first electronic device and the second electronic device.

In an implementation manner, if there is an intersection between the 5G channels supported by the two parties, the first channel negotiation module may negotiate, through the first bluetooth module, with the second channel negotiation module via the bluetooth channel to establish a 5G Wi-Fi connection on a certain 5G channel in the intersection, and then perform a data transmission process on the 5G channel. In one implementation, the first clone characteristic module may further send 5G hotspot opening information to the first connection module; the first connection module can send the 5G hotspot opening information to the first Wi-Fi module after receiving the 5G hotspot opening information, and instructs the first Wi-Fi module to open the 5G hotspot on a 5G channel supported by both sides. And then, the first electronic device and the second electronic device establish 5G Wi-Fi connection through the first Wi-Fi module and the second Wi-Fi module respectively, and finally the first electronic device and the second electronic device can perform data transmission on the 5G channel with the connection established through the first transmission module and the second transmission module respectively.

In another implementation manner, if there is no intersection between the 5G channels supported by the two parties (the data transmission method provided in this embodiment of the present application is mainly for this situation), the first channel negotiation module may generate 5G capability query information, where the 5G capability query information is used to query whether the second electronic device supports the 5G Wi-Fi communication capability. The first channel negotiation module sends the 5G capability inquiry information to the first Bluetooth module; after receiving the 5G capability query information, the first Bluetooth module can send the 5G capability query information to the second Bluetooth module through a Bluetooth channel.

And on the second electronic equipment side, the second Bluetooth module sends the 5G capability query information to the second channel negotiation module after receiving the 5G capability query information. After receiving the 5G capability query information, the second channel negotiation module may send the 5G capability query information to the second Wi-Fi short-range communication module through a general interface, where, for example, the general interface for 5G capability query may be: Wi-FiManager is5GHzBandSupported (). After receiving the 5G capability query information, the second Wi-Fi module may feed back a result of whether the second electronic device supports the 5GWi-Fi communication capability to the second channel negotiation module. Thereafter, the second channel negotiation module may transmit the 5G capability inquiry result to the second bluetooth module. After receiving the 5G capability inquiry result, the second bluetooth module may send the result to the first bluetooth module via a bluetooth channel.

On the first electronic device side, after receiving the 5G capability query result, the first bluetooth module may send it to the first channel negotiation module.

In some embodiments, if the 5G capability query result indicates that the second electronic device supports the 5G Wi-Fi communication capability, the first channel negotiation module may send channel probing information to the first channel probing module, and in response to the channel probing information, the first channel probing module may probe for 5G Wi-Fi connection requests of the second electronic device on 5G channels supported by the first electronic device itself, until the second electronic device performs 5G Wi-Fi connection, or completes the probing on all the supported 5G channels. If the first electronic device finds a 5G Wi-Fi connection request on a certain 5G channel, the two electronic devices can establish a 5G Wi-Fi connection on the 5G channel, and the subsequent first electronic device and the second electronic device can perform data transmission on the 5G channel; if the 5G Wi-Fi connection request of the second electronic device is not found on all 5G channels supported by the first electronic device, the first electronic device may close the 5G hotspot, open the 2.4G hotspot, establish Wi-Fi connection with the second electronic device on the 2.4G channel, and subsequently, the first electronic device and the second electronic device may perform data transmission on the 2.4G channel.

According to the data transmission method provided by the embodiment of the application, under the condition that the 5G channel supported by the second electronic device cannot be acquired, the first electronic device can sequentially search for the 5G Wi-Fi connection request of the second electronic device on the 5G channel supported by the local terminal, and try to establish 5G Wi-Fi connection with the second electronic device until the two sides of the 5G channel which can be successfully established are acquired. If after the attempt, all the 5G channels supported by the first electronic device cannot enable the two parties to successfully establish connection, the first electronic device may close the 5G hotspot, open the 2.4G hotspot, and establish Wi-Fi connection with the second electronic device on the 2.4G channel.

Illustratively, as shown in fig. 8, a timing diagram of a method for data transmission according to an embodiment of the present application is provided. The method comprises the following steps:

s801, a first UX display module receives a first operation input by a user.

The first UX display module is a module in a clone application installed in the first electronic device. The first electronic device may be, for example, a receiving device (or called receiving end) for receiving data in a switch cloning process, and is used to receive data that needs to be backed up by a user.

The first operation may be, for example, a receiver-side flow triggering operation input by the user through a clone application installed on the first electronic device in a switch-on-clone scenario, where the first operation may be, for example, a start operation of the clone application, or may also be an old device type selection operation in the clone application (which may correspond to operation 502 shown in fig. 5B).

First, at the receiving end, the first electronic device may perform the following steps:

and S802, the first UX display module sends receiving end process triggering information to the first clone characteristic module.

The receiving end flow triggering information is used for indicating the first clone characteristic module to start a switch clone flow of the receiving end. For example, the switch machine cloning flow of the receiving end may include: displaying a two-dimensional code comprising Wi-Fi hotspot connection information, establishing Bluetooth connection with a second electronic device, and the like.

And S803, responding to the receiving end process trigger information, and generating two-dimensional code information by the first clone characteristic module.

The two-dimension code information comprises Wi-Fi connection information of the first electronic device, such as an SSID and a password of a Wi-Fi hotspot. Specifically, the Wi-Fi connection information may be connection information of a 5G Wi-Fi hotspot, and may include an SSID of the 5G Wi-Fi hotspot and a corresponding password.

S804, the first clone characteristic module sends two-dimensional code information to the first UX display module.

And S805, the first UX display module indicates a display screen to display the two-dimensional code.

In some embodiments, after receiving the two-dimensional code information, the first UX display module may instruct the display screen to display a corresponding two-dimensional code, where the two-dimensional code is used to instruct Wi-Fi connection information (such as an SSID of a Wi-Fi hotspot and a corresponding password). For example, the interface of the first electronic device displaying the two-dimensional code may be as shown in fig. 5C.

Thereafter, at the transmitting end, the second electronic device may perform the following steps:

and S806, the second UX display module receives a second operation input by the user.

The second UX display module is a module in clone application installed in the second electronic device. The second electronic device may be a sending device (or called sending end) for sending data that needs to be backed up by a user when the clone is changed, and the second electronic device may be, for example, an old device of the user.

The second operation may be, for example, a sender flow triggering operation input by the user through a clone application installed by the second electronic device in a machine-changing clone scenario. For example, the second operation may be a two-dimensional code scanning interface opening operation input by the user through a clone application installed on the second electronic device, and the two-dimensional code scanning interface may be as shown in fig. 6, for example.

And S807, the second UX display module sends sending end flow triggering information to the second clone characteristic module.

And S808, the second clone characteristic module responds to the trigger information of the flow of the sending end to indicate that the camera is started.

For example, the second clone characteristic module may indicate a camera (e.g., a rear camera) of the second electronic device to be turned on in response to the sending-end flow trigger information, so as to perform two-dimensional code scanning next.

And S809, the second clone characteristic module sends two-dimensional code scanning interface starting information to the second UX display module.

And S810, the second UX display module indicates a display screen to display a two-dimensional code scanning interface.

In some embodiments, after receiving the two-dimensional code scanning interface opening information, the second UX display module may instruct the display screen to display the two-dimensional code scanning interface based on the information. Illustratively, the two-dimensional code scanning interface displayed by the second electronic device may be as shown in fig. 6, for example.

S811, the second electronic device scans the two-dimensional code of the first electronic device and obtains Wi-Fi connection information indicated by the two-dimensional code.

The second electronic device can scan the two-dimensional code displayed by the first electronic device through the two-dimensional code scanning interface. Then, the second UX display module may acquire Wi-Fi hotspot connection information indicated by the two-dimensional code, where the Wi-Fi hotspot connection information may include an SSID of a Wi-Fi hotspot of the first electronic device 5G and a corresponding password.

And S812, the second UX display module sends Wi-Fi connection information to the second clone characteristic module.

S813, the second clone characteristics module sends Wi-Fi connection information to the second Wi-Fi module.

And S814, the second Wi-Fi module tries to connect the Wi-Fi indicated by the Wi-Fi connection information according to the Wi-Fi connection information.

In some embodiments, if the second electronic device supports 5G Wi-Fi communication capability, after receiving the Wi-Fi connection information, the second Wi-Fi module may send Wi-Fi connection request information (e.g., a wifi prop request frame) on a 5G channel supported by itself according to the Wi-Fi connection information, and request to establish a connection with the first electronic device on the 5G Wi-Fi channel indicated by the connection information. For example, the second electronic device may periodically send Wi-Fi connection information through a 5G channel supported by the second electronic device, for example, the second electronic device may send a Wi-Fi connection request message on a certain 5G channel supported by the second electronic device, where the Wi-Fi connection request message may include an SSID of a Wi-Fi hotspot of the first electronic device and a corresponding password; when the Wi-Fi connection is not successfully established on the 5G channel, the second electronic device can switch to other 5G channels supported by the second electronic device to resend the Wi-Fi connection request message. When the 5G Wi-Fi connection with the first electronic device is not successfully established after traversing all the 5G channels supported by the second electronic device, the second electronic device may perform the Wi-Fi connection request process again at a certain time interval.

It should be noted that the sending of the Wi-Fi connection request information by the second electronic device may be continued until the connection with the 5G channel is successfully established with the first electronic device, or the connection with the first electronic device is established on the 2.4G channel. For example, the second electronic device sending the Wi-Fi connection information may be continuously performed during the process of the first electronic device querying the 5G channel list of the second electronic device, querying whether the second electronic device supports 5G capability, the first electronic device searching for Wi-Fi connection request information, and the like.

It should be further noted that, at the first electronic device side, the operation of sending the two-dimensional code information to the first UX display module by the first clone characteristic module may trigger the first clone characteristic module to send bluetooth activation information to the first bluetooth module. On the second electronic device side, the second clone-specific module acquires Wi-Fi connection information and can trigger the second clone-specific module to send Bluetooth starting information to the second Bluetooth module. Thereafter, the first electronic device and the second electronic device may perform a bluetooth connection establishment procedure.

S815, the first electronic device and the second electronic device perform a bluetooth connection establishment procedure.

For example, the bluetooth connection establishment process may refer to a schematic flowchart shown in fig. 9, and a specific process will be described below and will not be described in detail here.

In some embodiments, after the first electronic device and the second electronic device establish a bluetooth connection, the first electronic device may perform the following steps:

s816, the first electronic device performs a 5G channel list comparison process.

For example, the 5G channel list comparison process can refer to the schematic flowchart shown in fig. 10, and a specific process will be described below and will not be described in detail here.

It should be noted that after the first electronic device compares the 5G channel lists supported by both parties, two cases may exist in the obtained comparison result: in case 1A, the 5G channel lists of both parties have an intersection; in case 1B, there is no intersection between the 5G channel lists of both parties.

Case 1A and case 1B are introduced with specific channel list examples. In case 1A, it is assumed that the list of 5G channels supported by the first electronic device is: [ 3638404446132153157161165 ], the list of 5G channels supported by the second electronic device is: [ 36404448149463159161165 ], then the intersection of the 5G channels supported by the first electronic device and the second electronic device is: [36404448153161165]. In case 1B, assume that the list of 5G channels supported by the first electronic device is: [ 404448128132157165 ], the list of 5G channels supported by the second electronic device is: [ 364246149153155161 ], at this time, the intersection of the 5G channels supported by the first electronic device and the second electronic device is [ ], that is, the set of 5G channels supported by both devices is empty. Wherein, the element in the channel list is a channel number (channel number).

Optionally, when the 5G channel list fed back by the second electronic device is empty, the indication may also be expressed in other manners, for example, specific information (e.g., null) is carried in the channel response information sent by the second electronic device to the first electronic device to indicate that the channel list is empty, which is not limited in this embodiment of the application.

For case 1A, that is, when there is an intersection between the first electronic device and the supported 5G channel list of the second electronic device, the first electronic device may perform the following steps:

and S817, the first channel negotiation module sends 5G hotspot opening information to the first Wi-Fi module.

The 5G hotspot opening information is used for indicating the first Wi-Fi module to open the 5G hotspot.

For example, the specific process of the first channel negotiation module sending the 5G hotspot opening information to the first Wi-Fi module may include: the first channel negotiation module first sends the 5G hotspot opening information to the first connection module, and then the first connection module sends the 5G hotline opening information to the first Wi-Fi module (fig. 8 does not show the first connection module).

And S818, the first Wi-Fi module screens the 5G channels and starts a 5G hotspot.

In some embodiments, after receiving the 5G hotspot opening information, the first Wi-Fi module may perform 5G channel screening in an intersection of 5G channels supported by the first electronic device and the second electronic device, and open a 5G hotspot on the screened 5G channel. For example, when there are multiple 5G channels included in the intersection of the 5G channel lists of the first electronic device and the second electronic device, the first electronic device may select to open a 5G hotspot on the 5G channel where the signal strength is optimal.

For case 1B, that is, when there is no intersection between the first electronic device and the 5G channels supported by the second electronic device (for example, the 5G channel list fed back by the second electronic device is empty), the first electronic device may perform the following steps:

s819, the first electronic device queries whether the second electronic device supports the 5G capability.

For example, the capability query process of the second electronic device 5G can refer to the schematic flow chart shown in fig. 11, and the specific process will be described below and will not be detailed here.

Wherein the 5G capability query result of the second electronic device may include the following situations: case 2A, the second electronic device does not support the 5G capability; case 2B, the second electronic device supports 5G capabilities.

For case 2A, that is, when the second electronic device does not support the 5G capability, the first electronic device may perform the following steps:

s820, the first electronic device starts a 2.4G hotspot.

For case 2B, that is, when the second electronic device supports the 5G capability, the first electronic device may perform the following steps:

s821, the first electronic device searches Wi-Fi connection request information on a self-supported 5G channel and tries to establish 5G Wi-Fi connection with the second electronic device.

In some embodiments, the first electronic device may search for Wi-Fi Probe Request frames of the sending end one by one on a 5G channel already supported by the local end, wherein when a Probe Request frame of a specified SSID is received on a certain 5G channel, the 5G channel is selected to reply to Probe Response to initiate a 5G Wi-Fi connection with the second electronic device, and a 5G data transmission channel is established.

It should be noted that, in the process of searching for the Wi-Fi connection request information, the first electronic device is not affected by whether the first electronic device opens the 5G Wi-Fi hotspot, for example, the process may be performed in a situation that the first electronic device does not open the 5G Wi-Fi hotspot; alternatively, the method can also be carried out under the condition that the first electronic device turns on the 5G Wi-Fi hotspot.

The specific implementation process of the first electronic device searching for the Wi-Fi connection request information on the self-supported 5G channel will be described in more detail in the embodiment of fig. 12 below, and will not be described in detail here.

S822, the first electronic device and the second electronic device create a data transmission channel.

For example, the implementation process of step S820 in case 2A, step S821 in case 2B, and step S822 can refer to the schematic flowcharts shown in fig. 12 to fig. 14 below, and specific processes will be described below and will not be described in detail here.

It should be noted that in case 2A, that is, when the second electronic device does not support the 5G capability, the data transmission channel created by the first electronic device and the second electronic device in step S822 is a 2.4G channel, where the 2.4G channel is a 2.4G channel commonly supported by the first electronic device and the second electronic device. The process of establishing the 2.4G channel by the first electronic device and the second electronic device may refer to an existing flow, which is not described herein again. In case 2B, that is, when the second electronic device supports the 5G capability, after the first electronic device searches for the Wi-Fi connection request information of the sending end on the 5G channel supported by the local end and successfully establishes the 5G WiFi connection with the second electronic device, the data transmission channel of the first electronic device and the second electronic device is the 5G channel in step S822.

In some embodiments, after the first electronic device and the second electronic device establish the data transmission channel, the second clone character module may support the second UX display module to display the transmission data selection interface. For example, the transmission data display interface may include a plurality of application icons and selection frames, such as a contact icon, an information icon, a call record icon, an album icon, a mail icon, a WeChat icon, and their corresponding selection frames, which are selectable by the user, as shown in fig. 16A. In addition, the quantity and the size of information included by each application program can be respectively displayed below each application program, and a full selection box and a cancel box, a transmission starting control and a transmission canceling control can be further displayed below the application program display area.

It should be noted that the types of the application icons and the amount and size of the information corresponding to each application included in the transmission data selection interface shown in fig. 16A are merely examples, and are not limited.

S823, the second electronic device receives a third operation input by the user.

The third operation is transmission data selection operation input by a user and used for selecting files to be transmitted. The third operation may be, for example, a click operation of the user on a selection box corresponding to the application program in the interface shown in fig. 16A. Taking the data in the contact, the information, the call record, the photo album and the mail which need to be transmitted by the user as an example, the third operation may be an operation of clicking a selection frame in front of the contact icon, the information icon, the call record icon, the photo album icon and the mail icon by the user.

In some embodiments, after the user selects to transmit data, the first electronic device and the second electronic device may perform the following steps:

s824, the first electronic device and the second electronic device perform data transmission.

For example, the implementation process of step S824 can refer to the schematic flowchart shown in fig. 15 below, and a specific process will be described below and will not be detailed here.

According to the data transmission method provided by the embodiment of the application, the first electronic device can traverse the 5G channel supported by the first electronic device under the condition that the 5G channel supported by the second electronic device cannot be acquired, search for the 5G Wi-Fi connection request of the second electronic device, and try to establish 5G Wi-Fi connection with the second electronic device until the 5G channel which can be successfully established by both sides is acquired. If after the attempt, all the 5G channels supported by the first electronic device cannot enable the two parties to successfully establish connection, the first electronic device may close the 5G hotspot, open the 2.4G hotspot, and establish Wi-Fi connection with the second electronic device on the 2.4G channel.

The bluetooth connection establishment procedure in step S815 will be described below with reference to the accompanying drawings. Illustratively, as shown in fig. 9, a schematic flow chart of a process for establishing a bluetooth connection between a first electronic device and a second electronic device. The process comprises the following steps:

s8151, the first clone character module sends Bluetooth starting information to the first Bluetooth module.

In some embodiments, the operation of the first clone property module sending the two-dimensional code to the first UX display module (corresponding to step S804 described above) may trigger the first clone property module to send bluetooth activation information to the first bluetooth module, where the bluetooth activation information is used to instruct the first bluetooth module to activate the bluetooth function. More specifically, the bluetooth activation information may be used to instruct the first bluetooth module to perform a bluetooth connection function of the host device (i.e., the first electronic device).

And S8152, responding to the Bluetooth starting information, and the first Bluetooth module sends Bluetooth broadcast.

Accordingly, at the transmitting end, the second electronic device may perform the following steps:

and S8153, the second clone characteristic module sends Bluetooth starting information to the second Bluetooth module.

In some embodiments, the operation of the second clone property module obtaining Wi-Fi connection information (corresponding to step S812 above) may trigger the second clone property module to send bluetooth enable information to the second bluetooth module of the second electronic device, where the bluetooth enable information is used to instruct the bluetooth module to enable a bluetooth function. More specifically, the bluetooth activation information may be used to instruct the second bluetooth module to perform a bluetooth connection function of the slave device.

And S8154, responding to the Bluetooth starting information, and performing Bluetooth scanning by the second Bluetooth module.

And S8155, the second Bluetooth module and the first Bluetooth module establish Bluetooth connection.

The specific process of establishing the bluetooth connection may refer to the above related description, and is not described herein again.

It should be noted that, in the embodiment of the present application, a process of establishing a bluetooth connection is described by taking a first electronic device as a master device and a second electronic device as a slave device. However, in other embodiments, in the bluetooth connection establishment process, the first electronic device may also serve as a slave device, and the second electronic device may also serve as a master device, which is not limited in this embodiment of the present application.

It should be further noted that the bluetooth connection established between the first electronic device and the second electronic device is mainly used for negotiation between the two parties to perform Wi-Fi channel negotiation, for example, the first electronic device may query, through the bluetooth channel, a 5G channel supported by an opposite end, whether a 5G capability is supported, or not. In this embodiment of the present application, only a bluetooth connection is taken as an example, but in practical applications, the communication connection type used for Wi-Fi channel negotiation may be other types, which is not limited in this embodiment of the present application.

S8156, the first Bluetooth module sends Bluetooth connection establishment information to the first channel negotiation module, and the Bluetooth connection establishment information is used for indicating that Bluetooth connection establishment is completed.

After receiving the bluetooth connection information, the first channel negotiation module may perform a 5G channel comparison procedure in response to the bluetooth connection information (i.e., step S816). The following describes the 5G channel list comparison process in step S816 with reference to fig. 10. Illustratively, the process includes the steps of:

at the receiving end, the first electronic device may perform the following steps:

s8161, the first channel negotiation module sends first 5G channel query information to the first Bluetooth module, and the first 5G channel query information is used for querying a 5G channel supported by the second electronic device.

In some embodiments, the first channel negotiation module may send, to the first bluetooth module, first 5G channel query information in response to the bluetooth connection establishment information received in step S8156, where the first 5G channel query information is used to query a list of 5G channels (or a 5G channel set) supported by the second electronic device.

S8162, the first Bluetooth module sends the first 5G channel query information to the second Bluetooth module through the Bluetooth channel.

At the transmitting end, the second electronic device may perform the following steps:

and S8163, the second Bluetooth module sends the first 5G channel query information to the second channel negotiation module.

And S8164, the second channel negotiation module sends the first 5G channel query information to the second Wi-Fi module.

In some embodiments, the second channel negotiation module queries the second Wi-Fi module for 5G channels supported by the second electronic device in response to the first 5G channel query information.

In some embodiments, when the second electronic device does not have a general interface for querying the 5G channel, the second channel negotiation module may not successfully acquire the 5G channel query information that is successfully sent to the second Wi-Fi module, nor the 5G channel supported by the second electronic device and fed back by the second Wi-Fi module. At this time, the second channel negotiation module may generate a 5G channel list, and the 5G channel list is empty, that is, the 5G channel list does not include the 5G channels supported by the second electronic device.

It should be noted that, in an actual application, when the clone application is a third-party application installed on the second electronic device, and the second electronic device does not have a general interface for querying the 5G channel, in the process of changing the switch and cloning, even if the clone application is installed on the second electronic device, the clone application cannot query the 5G channel list supported by the second electronic device, and further cannot enable the first electronic device to select the 5G channel for data transmission based on the intersection of the 5G channels supported by the two sides. The data transmission method provided by the embodiment of the application can solve the problem that the 5G channel cannot be negotiated in the scene. Therefore, the present embodiment is mainly described in terms of a situation where the first electronic device cannot inquire about the 5G channel supported by the second electronic device (for example, a situation where the 5G channel list fed back by the second electronic device is empty).

S8165, generating first 5G channel response information.

In some embodiments, when the second channel negotiation module does not inquire the 5G channel supported by the second electronic device, first 5G channel response information is generated, where the first 5G channel response information includes a list of 5G channels supported by the second electronic device, and the list of 5G channels is empty.

In some embodiments, the second electronic device may send an empty 5G channel list to the first electronic device through the first 5G channel response information.

Optionally, the second electronic device may also indicate that the second electronic device does not query the 5G channel supported by the second electronic device by carrying other indication information (e.g., null) in the first 5G channel response information, and the embodiment of the present application does not limit how to specifically indicate that the second electronic device does not query the 5G channel.

S8166, the second channel negotiation module sends the first 5G channel response information to the second Bluetooth module.

S8167, the second Bluetooth module sends the first 5G channel response information to the first Bluetooth module through the Bluetooth channel.

s8168, the first bluetooth module sends the first 5G channel response information to the first channel negotiation module.

In some embodiments, the first channel negotiation module may obtain a 5G channel list supported by the second electronic device according to the 5G channel response information.

S8169, the first channel negotiation module sends second 5G channel query information to the first Wi-Fi module, and the second 5G channel query information is used for querying a 5G channel supported by the first electronic device.

S81610, the first Wi-Fi module sends second 5G channel response information to the first channel, and the second 5G channel response information comprises a 5G channel list supported by the first electronic device.

It should be noted that the steps (i.e., step S8169 and step S81610) of the first electronic device acquiring the self-contained 5G channel list are not limited to be executed after acquiring the 5G channel list (corresponding to steps S8161 to S8168) of the second electronic device. In other embodiments, the operation of querying the own 5G channel list by the first electronic device may be performed simultaneously with the operation of querying the second electronic device 5G channel list, or may be performed before querying the second electronic device 5G channel list, which is not limited in this embodiment of the application.

And S81611, determining that the 5G channel set supported by the two parties is empty.

In some embodiments, the first channel negotiation module of the first electronic device compares the list of 5G channels supported by the first electronic device with the list of 5G channels supported by the second electronic device, and determines that the set of 5G channels supported by both of the first electronic device and the second electronic device is empty.

For example, assume that the list of 5G channels supported by the first electronic device is: 3638404446132153157161165, the list of 5G channels supported by the second electronic device is empty, that is [ ], and then the first channel negotiation module may determine the set of 5G channels supported by both of the first electronic device and the second electronic device as empty [ ] according to the list of 5G channels supported by the first electronic device and the list of 5G channels supported by the second electronic device. Or, when the first channel response information carries specific indication information (e.g., null) indicating that the second electronic device does not inquire the 5G channel of the second electronic device, the first channel negotiation module may determine that the 5G channel set jointly supported by the two electronic devices is empty according to the 5G channel list supported by the first electronic device and the specific indication information carried in the first response information.

It should be noted that, in other embodiments, after the first electronic device receives the first channel list, if it is determined that the first channel list is empty, the comparison operation on the first channel list and the second channel list may not be performed, and it may be directly determined that the 5G channel set commonly supported by the first electronic device and the second electronic device is empty.

It should be further noted that, in still other embodiments, after the first electronic device receives the first channel list, if it is determined that the first channel list is empty, the operation of determining that the set of 5G channels supported by the first electronic device and the second electronic device are empty may not be performed, and the next step in the flow is performed (e.g., step S8181). In other words, if the first channel list acquired by the first electronic device is empty, the first electronic device may be triggered to execute a query process for the 5G capability of the second electronic device.

When there is no intersection between the first electronic device and the second electronic device that supports the 5G channels (e.g., the list of 5G channels fed back by the second electronic device is empty), the first electronic device may query the second electronic device for the 5G capability (corresponding to step S819 described above). The 5G capability query process of the second electronic device in step S819 is described below with reference to fig. 11. Illustratively, the process includes the steps of:

s8181, the first channel negotiation module sends 5G capability query information to the first Bluetooth module, and the 5G capability query information is used for querying whether the second electronic device supports 5G capability.

In some embodiments, the first channel negotiation module may send the 5G capability query information to the first bluetooth module when determining that the set of 5G channels supported by both parties is empty in step S81611.

S8182, the first bluetooth module sends the 5G capability inquiry information to the second bluetooth module via the bluetooth channel.

and S8183, the second Bluetooth module sends 5G capability inquiry information to the second channel negotiation module.

And S8184, the second channel negotiation module sends the 5G capability inquiry information to the second Wi-Fi module.

It should be noted that the second electronic device has a common interface for 5G capability query, where the common interface may be, for example: Wi-FiManager is5GHzBandSupported (). After the second channel negotiation module receives the 5G capability query message, the 5G capability query message may be sent to the second Wi-Fi module via the general interface, so as to query whether the second electronic device supports the 5G capability.

And S8185, the second Wi-Fi module sends 5G capability response information to the second channel negotiation module.

Wherein the 5G capability response information includes a query result of whether the second electronic device supports the 5G capability. Optionally, when the second electronic device does not support the 5G capability, the capability supported by the second electronic device, such as the 2.4G capability, may also be indicated in the 5G capability response information.

And S8186, the second channel negotiation module sends 5G capability response information to the second Bluetooth module.

S8187, the second bluetooth module sends the 5G capability response message to the first bluetooth module.

Thereafter, at the receiving end, the first electronic device may perform the following steps:

s8188, the first bluetooth module sends 5G capability response information to the first channel negotiation module.

In some embodiments, the first channel negotiation module may obtain a query result of whether the second electronic device supports the 5G capability according to the 5G capability response information.

According to different query results, two situations can be distinguished: case 2A, the second electronic device does not support the 5G capability; case 2B, the second electronic device supports 5G capabilities.

Illustratively, as shown in fig. 12, a schematic flow chart is shown for the first electronic device to perform corresponding operations in case 2A and case 2B described above, respectively.

s8201, the first channel negotiation module sends 2.4G hotspot opening information to the first Wi-Fi module.

The 2.4G hotspot opening information is used for indicating the first Wi-Fi module to open the 2.4G hotspot.

In some embodiments, the specific process of the first channel negotiation module sending the 2.4G hotspot opening information to the first Wi-Fi module may include: the first channel negotiation module sends the 2.4G hotspot opening information to a first connection module of the first electronic device; then, the first connection module sends the 2.4G hotspot opening information to a first Wi-Fi module (the first connection module may specifically refer to fig. 7, and the first connection module is not shown in fig. 12).

S8202, the first Wi-Fi module conducts 2.4G channel screening, and a 2.4G hotspot is opened.

The Wi-Fi module of the first electronic device can respond to the 2.4G hotspot opening information, perform 2.4G channel screening, and open the 2.4G hotspot based on the screened 2.4G channel.

Exemplary, the screening of the 2.4G channel may include: the method selects a channel with the best signal strength from the 2.4G channels supported by both parties according to the signal strength, or performs random selection from the 2.4G channels supported by both parties, which is not limited in the embodiment of the present application.

optionally, in S8211, the first channel negotiation module instructs the timer to set a preset time duration.

For example, the preset time period may be 30s, 40s, 1min, and the like, which is not limited in the embodiment of the present application. The preset time length is used for the first electronic equipment to search Wi-Fi connection request information at a squatting point on a 5G channel supported by the local terminal, and to try to establish Wi-Fi connection with the second electronic equipment on the 5G channel.

In some embodiments, if the first electronic device does not seek the Wi-Fi connection request within the preset time period, the first electronic device and the second electronic device may be considered to have no commonly supported 5G channel, and the first electronic device may turn on a 2.4G Wi-Fi hotspot and perform data transmission with the second electronic device on the 2.4G channel.

It should be noted that step S8211 is an optional step, that is, the first electronic device may also directly and sequentially search for the Wi-Fi connection request information at the squat point on the 5G channel supported by the first electronic device without setting the preset time duration until the Wi-Fi connection request is successfully searched, or all 5G channels are traversed.

S8212, the first channel negotiation module sends channel probing indication information to the first channel probing module.

The channel detection information is used for instructing the first channel detection module to search the Wi-Fi connection request information on a 5G channel supported by the home terminal of the first electronic device.

In some embodiments, the manner for triggering the first channel negotiation module to send the channel sounding information to the first channel sounding module may include multiple manners, such as: after the first channel negotiation module obtains the 5G capability supported by the second electronic device, the first channel negotiation module can send channel detection indication information to the first channel detection module; alternatively, the first channel negotiation module may send the channel sounding indication information to the first channel sounding module when the indication timer starts to count.

S8213, the first channel detection module searches for Wi-Fi connection request information on a 5G channel supported by the home terminal of the first electronic device.

In some embodiments, the first channel probing module may query, by the first Wi-Fi module, a 5G channel supported by the first electronic device after receiving the channel probing information sent by the first channel negotiation module; alternatively, the first channel negotiation module may carry the 5G channels supported by the first electronic device in the channel finding information.

Then, the first channel detection module may sequentially squat at a point on the 5G channel supported by the first electronic device to query whether Wi-Fi connection request information is received on the currently queried 5G channel. For example, the first channel sounding module may stay on each 5G channel for a target duration in turn, and search for whether the Wi-Fi connection request information is received within the target duration.

In some embodiments, the first channel sounding module may sequentially seek Wi-Fi connection request information on the 5G channels according to numbers (e.g., numbers from small to large) of the 5G channels supported by the first electronic device.

For example, it is assumed that the numbers of the 5G channels supported by the first electronic device are: 3638404446132153157161165, the first channel sounding module may first wait for a target duration (e.g., 2 s) on channel # 36, 5G, to query whether Wi-Fi connection request information is received within the target duration. If the Wi-Fi connection request information is received, inquiring whether the Wi-Fi connection information (such as an SSID (service set identifier) and a corresponding password) carried by the Wi-Fi connection request information is the connection information of the 5G Wi-Fi hotspot of the first electronic device, if so, sending Wi-Fi connection Response information (Probe Response) by the first electronic device, and initiating Wi-Fi connection; if not, after the target duration is reached, the first channel detection module may switch to the 5G channel with the next number (number 38) to continue searching, and repeat the searching process until the first channel detection module obtains the Wi-Fi connection request including the connection information of the 5G Wi-Fi hotspot of the first electronic device; or when the Wi-Fi connection request comprising the connection information of the 5G Wi-Fi hotspot of the first electronic device is not continuously acquired, until the first channel detection module traverses all the supported 5G channels; or when the Wi-Fi connection request of the connection information of the first electronic device 5G Wi-Fi hotspot is not acquired continuously, the preset target time length is reached.

When the first channel detection module detects Wi-Fi connection request information including 5G Wi-Fi hotspot connection information of the first electronic device on a 5G channel supported by the home terminal, the first electronic device may establish Wi-Fi connection with the second electronic device on the 5G channel. For the convenience of distinction, the embodiment of the present application refers to the 5G channel which detects the Wi-Fi connection request information including the 5G Wi-Fi hotspot connection information of the first electronic device as a first channel. Specifically, the first electronic device may perform the steps of:

In some embodiments, the first Wi-Fi module opens the 5G hotspot on the first channel in response to the 5G hotspot opening information, and establishes a data transmission channel with the second electronic device. The creation process of the data channel may be as shown in fig. 14 below, and a specific process will be described below, which will not be described in detail here.

In some embodiments, if the first electronic device and the second electronic device do not successfully establish the 5G Wi-Fi connection, the first electronic device switches to the 2.4G hotspot and establishes a 2.4G connection with the second electronic device. Wherein, the situation of unsuccessfully establishing the 5G Wi-Fi connection can comprise: (1) after traversing all 5G channels supported by the local terminal, the first electronic equipment does not receive Wi-Fi connection request information comprising 5G Wi-Fi connection information of the first electronic equipment; (2) the first electronic device does not receive Wi-Fi connection request information comprising 5G Wi-Fi connection information of the first electronic device within a preset target time length.

In some embodiments, the user may select the data to be backed up to the first electronic device by inputting a data selection operation (corresponding to the third operation) to be transmitted on the interface.

It should be noted that, in the embodiment of the present application, a sequence of the first electronic device performing steps S8222 to S8225 and the second electronic device performing steps S8226 to S8229 is not limited, in other words, after the Wi-Fi connection is established, the first electronic device and the second electronic device may perform respective operations independently.

s1701, the first electronic device establishes a communication connection with the second electronic device, and obtains a first channel list of the second electronic device, where the first channel list is used to indicate a first target frequency band channel supported by the second electronic device.

The communication connection established between the first electronic device and the second electronic device may be a bluetooth connection. The specific process of establishing the communication connection between the first electronic device and the second electronic device may refer to the description in the embodiments of fig. 8 and fig. 9, and is not described herein again.

In some embodiments, the first electronic device may be a data receiving device in a switch clone scenario, and the second electronic device may be a data sending device in a switch clone scenario. The first electronic device is a device that supports the first target frequency band capability, that is, the first electronic device supports the capability of Wi-Fi communication on the first target frequency band. The first target frequency band may be a 5G frequency band, and the first target frequency band channel may be a 5G channel.

In some embodiments, the first channel list may correspond to the 5G channel response information in the foregoing embodiments, and may specifically be used to indicate the first target frequency band channel supported by the second electronic device.

In some embodiments, the first electronic device may receive a first operation input by a user, and the first operation may be, for example, a receiving end flow opening operation, such as operation 501 shown in fig. 5A; or may be an old device type selection operation entered by the user in the clone application, which may correspond to operation 502 shown in fig. 5B, for example.

In some embodiments, the first electronic device, in response to the first operation, may display a two-dimensional code for providing connection information of a Wi-Fi hotspot of the first electronic device, such as an SSID of the Wi-Fi hotspot and a corresponding password.

In some embodiments, the second electronic device may receive a second operation input by the user, where the second operation may be, for example, a two-dimensional code scanning interface opening operation of the second electronic device, where the two-dimensional code scanning interface may be, for example, as shown in fig. 6; responding to the second operation, and displaying a two-dimensional code scanning interface by the second electronic equipment; then, the second electronic device may scan the two-dimensional code displayed by the first electronic device through the two-dimensional code scanning interface, and then extract the SSID of the Wi-Fi hotspot and the password provided by the two-dimensional code (which may correspond to the two-dimensional code data in the above-mentioned embodiment, or Wi-Fi hotspot connection information).

In some embodiments, the first electronic device and the second electronic device may establish a bluetooth connection. For example, the first electronic device may send a bluetooth inquiry request in response to a two-dimensional code display operation or in response to an operation that a two-dimensional code is scanned; the second electronic device can respond to the two-dimension code scanning interface starting operation or respond to the two-dimension code scanning operation to carry out Bluetooth scanning; after that, the first electronic device and the second electronic device may establish a bluetooth connection based on a bluetooth communication standard, and a specific process of establishing the bluetooth connection may refer to the above related description, which is not described herein again.

Then, in some embodiments, the first electronic device may send first channel query information to the second electronic device via the bluetooth channel, where the first channel query information is used to query a first target frequency band channel supported by the second electronic device; the second electronic equipment receives first channel query information sent by the first electronic equipment through a Bluetooth channel; in response to the first channel query information, the second electronic device may query a first target frequency band channel supported by the second electronic device; thereafter, the second electronic device may transmit first channel response information to the first electronic device via the bluetooth channel, the first channel response information including the first channel list. Wherein the first channel query information may correspond to the 5G channel query information in the above embodiment.

In some embodiments, when the second electronic device fails to query the first target frequency band channel (for example, the second electronic device does not have a channel query generic interface, so that the first target frequency band channel cannot be queried), the first target frequency band channel included in the first list is empty, and the list of 5G channels that may correspond to the above-described feedback of the second electronic device is empty.

And S1702, when an intersection of the first channel list and a first target frequency band channel supported by the first electronic device is empty, sequentially inquiring whether Wi-Fi connection request information sent by the second electronic device is received on the first target frequency band channel supported by the first electronic device, wherein the Wi-Fi connection request information is used for requesting to connect to a Wi-Fi hotspot of the first electronic device in the first target frequency band.

In some embodiments, the first electronic device may obtain a second channel list, where the second channel list may be used to indicate the first target frequency band channel supported by the first electronic device itself. Specifically, the first channel negotiation module of the first electronic device may send a second channel query message to the first Wi-Fi module and receive a second channel response message sent by the first Wi-Fi module, and the second channel response message may include a second channel list.

In some embodiments, the first electronic device may obtain that an intersection of the first channel list and the second channel list is empty according to the first channel list and the second channel list. The intersection of the first channel list and the second channel list being empty may indicate that the first electronic device and the second electronic device do not have the first target frequency band channel commonly supported, that is, the first target frequency band channel set commonly supported by the first electronic device and the second electronic device is empty.

In some embodiments, when an intersection of a first target frequency band channel supported by the first electronic device and a first target frequency band channel supported by the second electronic device is empty, the first electronic device may sequentially query, on the first target frequency band channel supported by the first electronic device, whether Wi-Fi connection request information sent by the second electronic device is received, where the Wi-Fi connection request information may include Wi-Fi hotspot connection information of the first electronic device on the first target frequency band, for example, an SSID of the Wi-Fi hotspot and a corresponding password, and the Wi-Fi connection request information is used to request connection of a Wi-Fi hotspot of the first electronic device on the first target frequency band.

In some embodiments, the triggering of the first electronic device to perform a sequential query on a first target frequency band channel supported by the first electronic device whether Wi-Fi connection request information sent by the second electronic device is received may include: setting a preset time length; if the Wi-Fi connection request information sent by the second electronic equipment is not received within the preset time length, establishing Wi-Fi connection with the second electronic equipment on a second channel at a second target frequency band; or if the Wi-Fi connection request information sent by the second electronic equipment is not received after all the first target frequency band channels supported by the first electronic equipment are traversed and the Wi-Fi connection request information is inquired, establishing Wi-Fi connection with the second electronic equipment on a second channel by using the second target frequency band channel.

The second target frequency band may be a 2.4G frequency band, and the second channel may be a certain second target frequency band channel supported by the first electronic device and the second electronic device.

In some embodiments, the manner that the first electronic device sequentially queries, on the first target frequency band channel supported by the first electronic device, whether the Wi-Fi connection request information sent by the second electronic device is received may include: the first electronic device may wait for a preset target duration in sequence on a first target frequency band channel supported by the first electronic device; and whether the Wi-Fi connection request information sent by the second electronic equipment is received or not is detected in the target time length.

In some embodiments, before the first electronic device sequentially inquires whether the Wi-Fi connection request information sent by the second electronic device is received on the first target frequency band channel supported by the first electronic device, the method may further include: when the first electronic device acquires that the intersection of the first channel list and the second channel list is empty, the first electronic device may send capability query information (which may correspond to the 5G capability query information in the foregoing embodiment) to the second electronic device, where the capability query information is used to query whether the second electronic device supports the first target frequency band capability; the second electronic device may obtain, in response to the capability query information, a query result of the first target frequency band capability, where the query result may be that the second electronic device supports the first target frequency band capability, and then, the second electronic device sends, to the first electronic device, capability response information (which may correspond to the 5G capability response information in the above embodiment) indicating that the second electronic device supports the first target frequency band capability; then, the first electronic device receives capability response information sent by the second electronic device, and acquires that the second electronic device supports the first target frequency band according to the capability response information; and then, the first electronic equipment starts a first target frequency point Wi-Fi hotspot on the first channel.

It should be noted that, in this embodiment of the application, the second electronic device has a general interface for querying a capability of the first target frequency band (for example, 5G), and therefore, the first electronic device may obtain the capability of the first target frequency band of the second electronic device.

It should be further noted that, before the first electronic device attempts to establish the Wi-Fi connection with the second electronic device on the first channel, by querying the second electronic device for the first target frequency band capability, and after determining that the second electronic device supports the first target frequency band capability, establishing the Wi-Fi hotspot on the first channel, the possibility that the two parties successfully establish the Wi-Fi connection on the first target frequency band channel can be further improved.

S1703, if the Wi-Fi connection request information is received on the first channel, establishing a first target frequency band Wi-Fi connection on the first channel with the second electronic device, where the first channel is a channel on a certain first target frequency band supported by the first electronic device.

The Wi-Fi connection request message comprises an SSID and a corresponding password, and can be used for requesting connection to a first target frequency band Wi-Fi hotspot of the first electronic device.

In some embodiments, after acquiring the SSID of the Wi-Fi hotspot of the first electronic device and the corresponding password, the second electronic device may send a polling message for establishing the Wi-Fi connection request on a first target frequency band supported by the second electronic device. Specifically, the second electronic device may periodically traverse a first target channel supported by itself, attempting to establish a Wi-Fi connection (of the first target frequency band) with the first electronic device. For example, the second electronic device may broadcast a Wi-Fi connection request message on a certain first target frequency channel supported by the second electronic device, where the broadcast message of the Wi-Fi connection request may include an SSID and a password of a Wi-Fi hotspot of the first electronic device (of the first target frequency channel); if the Wi-Fi connection is not successfully established on the first target frequency band channel, switching to other first target frequency band channels to rebroadcast the Wi-Fi connection request message. When the Wi-Fi connection with the first electronic device is not successfully established after traversing all the first target frequency band channels supported by the second electronic device, the Wi-Fi connection request process may be performed again at a certain time interval.

S1704, data transmitted by the second electronic device via the first channel is received.

The data transmitted in the embodiment of the application can be the data which is selected by the user and needs to be backed up to the first electronic device. The data transmission process can be referred to the specific description of the above embodiments.
